Web1 day ago · I know that in C/C++ arrays should be allocated into the stack, as they are static data structures, so if I write: int a [2]; the space needed to store 2 integer numbers should be allocated into the stack. But if we consider the situation where the dimension is, for example, taken from user input, like the following one: int dim; cout << "Tell ... WebThe most important difference is that the size of a regular array needs to be a constant expression, and thus its size has to be determined at the moment of designing the program, before it is run, whereas the dynamic memory allocation performed by new allows to assign memory during runtime using any variable value as size.
